I have been playing with my suspension and fitted new front tyres lately. I am running Gaz Gold. They are 6 clicks away from full hard at moment, 22 clicks range on the front, so you could say they are at 73% stiffness if that makes sense! Rears are set up the same. I have also fitted new Rainsport 3 tyres on the front, these seem to be a very soft tyre with a fair degree of sidewall flex evident, for example if you rock the car when it is stationary it will wibble a bit side to side on the front tyres. Was on the motorway at the weekend at cruising about 80mph the car seemed very bouncy over undulations. Not worn shocker bouncy, just seemed to be making a bigger deal of the undulations than I can remember from before. Not evident at slow speeds or much evident really at higher speeds. I had been running 32psi all round but hiked the fronts up to 36psi to see if that helped, but never made a whole lot of difference.

Anyway, do we think I need to stiffen the shocks further or could it be the tyres causing this? Can't say I noticed overly when driving as it still felt pretty planted, it was more the good lady suggesting she should have worn a sports bra!

Anwers on a postcard!

no damping in the tyre bounce you might need to soften the compression damping a bit

Cheers. Probably have it set up for a nice smooth track at present. I'll notch it back a couple of clicks and should be fine for fast road.

The shocks sound stiff and not absorbing the bumps. The Tyres may then bouncing.
